Sorry, but I have no time to build modules. The easiest way to have it to build it from a standard ESP32-devkit-c module. The only need is a chip (SN75176) which transfers the UART of the ESP to RS-485 which is used by HiSense.
Ah, now i see what is U1 on your schematics diagram. It's SNx5176B, right? I wasn't able to understand BOM for your schematics. Would be great if you can update with all components nominals, if possible.
Great project! Love the idea of local access.
Did you consider to sell your Wi-Fi modules? I would buy couple modules from you.
